Muntilingualizaion of w3m
2003/03/08
H. Sakamoto
Introduction
I have tried the multilingualization of w3m (w3m-m17n).
The patch for w3m-0.4.1 is available on the following site.
http://www2u.biglobe.ne.jp/~hsaka/w3m/index.html#m17n
patch/w3m-0.4.1-m17n-20030308.tar.gz
patch/README.m17n
This is a development version, and should be enough to test.
I can understand Japanese only, so please use this version, test it,
and report bugs.
Now, w3m-m17n has following functions.
Supported encoding schemes (character set)
* Japanese
EUC-JP - US_ASCII, JIS X 0208, JIS X 0201, JIS X 0212
(EUC-JISX0213) (JIS X 0213)
ISO-2022-JP - US_ASCII, JIS X 0208, JIS X 0201, JIS X 0212, etc.

* Unicode (UCS-4)
UTF-8, UTF-7
NOTE:
* The left part of JIS X 0201 and GB 1988 (Chinese ASCII) are
treated as US_ASCII because they are used in tags of HTML document.
Another variant of US_ASCII is treated without change.
* JIS C 6226(old JIS) is treated as JIS X 0208.
* The sequence '~\n' of HZ is not supported.
Display
There are two method for multilingual diplay.
(1) kterm + ISO-2022-JP/CN/KR
* kterm can handle JIS X 0213, CNS 11643, if the following patch
is applied.
http://www.st.rim.or.jp/~hanataka/kterm-6.2.0.ext02.patch.gz
* Specify the fontList for kterm with -fl option or in ~/.Xdefaults.
-fl "*--16-*-jisx0213.2000-*,\
*--16-*-jisx0212.1990-0,\
*--16-*-ksc5601.1987-0,\
*--16-*-gb2312.1980-0,\
*--16-*-cns11643.1992-*,\
*--16-*-iso8859-*"
Fonts of JIS X 0213 exist in
http://www.mars.sphere.ne.jp/imamura/jisx0213.html
* Set the "display_charset" to ISO-2022-JP(or ISO-2022-JP-2, KR, CN),
and "strict_iso2022" to OFF on the option pannel. (see below)
(2) xterm + UTF-8
* Use xterm (xterm-140 or later) of XFree86.
http://www.clark.net/pub/dickey/xterm/xterm.html
* Fonts of Unicode exist in
http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html
http://openlab.ring.gr.jp/efont/index.html.en
* Use xterm with -u8 option.
The fonts are specified such as
-fn "*-medium-*--13-*-iso10646-1" \
-fb "*-bold-*--13-*-iso10646-1" \
-fw "*-medium-*-ja-13-*-iso10646-1"
* Set the "display_charset" to UTF-8.
And, it is better that "pre_conv" is ON.
(3) mlterm + ISO-2022-JP/KR/CN
* Homepage
http://mlterm.sourceforge.net/
* Set encoding of mlterm to ISO-2022-JP/KR/CN or UTF-8.
* Set the "display_charset" to ISO-2022-JP/KR/CN or UTF-8.

* EUC-KR <-> ISO-2022-KR <-> Johab (only Symbol and Hanja)
Other conversions are based on Unicode.
Change document charset
Press '=' (show document infomation), and select document charaset.
If you specify the following keymaps,
keymap C CHARSET
keymap M-c DEFAULT_CHARSET
you can press `C' to change the current document charset,
and `M-c' to change the default document charset.
Line Editing
Input coding system is followed by display coding system.
NOTE:
* HZ can not be used as input coding system.
* Input with ISO-2022-CN or ISO-2022-KR is perhaps failure, because
SI(\017) and SO(\016) are already assigned as other command key.
(SO is assigned as `next-history'). If you want to use SI and SO,
press C-@(^@). After that, SI, SO, SS2, SS3, LS2, and LS3 of
7bit ISO-2022 are recognited. When you press C-@ again, the default
binding is set.
Regular expression
Multilingual regular expression is supported.
